<h2><a name="Requirements"></a>Requirements</h2>
<p>SchemaQualityChecker (SQC) and QualityChecker (QC) API require
a Java Runtime Environment (JRE) version 1.3 or greater.</p>
<p>IBM's version of the JRE (1.3) can be downloaded after registering
at <a href="http://www6.software.ibm.com/dl/wspt/wspt-p/">WebSphere
Preview Technologies</a> and Sun's version can be obtained at <a
href="http://java.sun.com/j2se/1.4/jre/" target="_top" >http://java.sun.com/j2se/1.4/jre/</a>.
IBM's JRE comes with a xerces.jar and xml4j.jar files
included. These files should be moved to another directory.</p>
<p>The <i>xmlParserAPIs.jar</i>, <i>xercesImpl.jar</i> and <i>xml4j.jar</i> files included in the Schema Quality Checker distribution
package should be used to avoid run-time errors.</p>
<p>Users who would like to use Microsoft's Internet Explorer to
see the XML report generated by SchemaQualityChecker with the
stylesheet provided in the distribution package, should use either
version 5.5 and
<a href="http://msdn.microsoft.com/downloads/default.asp?URL=/code/sample.asp?url=/MSDN-FILES/027/001/591/msdncompositedoc.xml">MSXML 3.0</a>
(installed in replace mode) or
<a href="http://www.microsoft.com/windows/ie/" target="_top">version 6.0</a>.</p>
